Summary
Three-dimensional light microscopy and the excellent
cytological features of maize melotic chromosomes
are used to analyze the early events of chromosome
synapsis. We demonstrate that the chromosomes un-
dergo a dramatic structural reorganization prior to syn-
apsis in zygotene. The unique features of prezygotene
chromosomes are a partial separation of sister chro-
